GROW (A Group for Research on Wireless) has been established more than 20 years ago, with the purpose of giving a framework to people to work on R&D in the area of mobile and wireless communications, not only for developing their theses (either M.Sc. or Ph.D.) as students, but also to pursue a career as researchers working in projects. During this period, more than 160 students developed their theses within GROW, and more than 40 projects (funded by either the European Commission or Portuguese companies) were executed, providing an average funding of nearly 400 k€/year, and enabling to have for more than a decade a permanent team of at least 7 people fully supported by these projects (besides other collaborators), resulting in more than 400 publications. These have been great times, but times change.

“Time changes, and our desires change. What we

believe — even what we are — is ever

changing. The world is change, which forever

takes on new qualities. And constantly,

we see the new and the novel overturning

the past, unexpectedly, while we retain

from evil, nothing but its terrible pain,

from good (if there’s been any), only the yearning.

Time covers the ground with her cloak of green

where, once, there was freezing snow—and rearranges

my sweetest songs to sad laments. Yet even more

astonishing is yet another unseen

change within all these endless changes:

that for me, nothing ever changes anymore.”

Luis de Camões (Portuguese poet, 1524/1580).

In the last couple of years, it was not possible to succeed in getting projects to sustain the activity of the permanent R&D team. The projects running in the past years have finished in October and November, hence, this team has also finished its activity by the end of this December, and they will be progressing their professional careers elsewhere. I’m talking about Lúcio Ferreira, Carla Oliveira, Daniel Sebastião, and Mónica Antunes. Life as we knew it in GROW will never be the same, but life goes one.

“Every morning in Africa, a gazelle wakes up.

It knows it must run faster than the fastest lion,

or it will be eaten.

Every morning in Africa, a lion wakes up.

It knows it must run faster than the slowest gazelle,

or it will starve to death.

 It doesn’t matter whether you are a lion or a gazelle;

when the sun comes up, you’d better be running.”

African tale.

GROW keeps its activity with the colleagues and the supporting staff, as well as the Ph.D. and M.Sc. Students, that are still developing their work in it.

Let’s keep in touch.

Bringing your attention to a matter in this issue of the Newsletter

The increase in network costs and in the total data traffic will be quite a limitation for mobile networks operators in the future, especially with the introduction of LTE-A. Consequently, it is necessary to innovate and upgrade network architectures, focusing mainly on the Radio Access Networks (RANs). Green and centralised RANs are the solution, since they will be constituted by datacentres that use virtualisation techniques in order to simulate base stations (BSs), thus, decreasing maintenance costs and improving some main aspects on the flow of signalling and control information. The impact of introducing a centralised cloud based architecture in an urban scenario was analysed, and a model for the deployment of the infrastructure required for this novel architecture was developed, starting from the current deployment of an existing network.

Concentrating computational capacity in BBUs (Baseband Processing Units) introduces a new segment in the traditional RAN architecture, implying that time constraints provided by specifications for tasks accomplished by eNodeBs must incorporate also the time for the transportation of data through the fronthaul segment. The budget of time for transportation represents a key aspect for the deployment optimisation, because it has a direct impact on the maximum length of the links between RRHs (Remote Radio Heads) and BBUs. Designing a solution for an urban scenario raises an important requirement: not all the locations that could be considered optimal for the BBU pools positions should be able to host the infrastructures required for a BBU pool, due to the fact that network operators cannot locate equipment in arbitrary locations, such as protected buildings, difficult geographical locations, and so on. The adopted approach to avoid this problem is to consider as the set of feasible positions for the BBUs the set of locations of the existing BSs.

Picture6The figure shows how the developed algorithm placed the BBU Pools (in red) in the scenario of the greater Lisbon, for a maximum fronthaul delay constraint of 30 μs; the blue dots represent the cell sites where the RRHs are placed. The number of BBU Pools decreases as the maximum fronthaul delay increases, roughly following an inverse proportionality model.

Bringing your attention to a matter in this issue of the Newsletter

The nowadays continuously increasing number of mobile users, devices and new mobile applications has resulted in the mobile data traffic growing at an unprecedented rate, which alternatively has a significant impact on the complexity of processes required to provide reliable cellular networks. Over the last few years, mobile operators are struggling to cope with these challenges. Still they rely on highly centralised and custom hardware components that are not designed with elasticity in mind, leading to a weak optimisation of resources during non-peak hours and frequent overloads during peak hours. A model was proposed for network performance, comparison the location of data centres in an LTE-A network with an implementation of a virtualised infrastructure, by separating base stations into Remote Radio Heads (RRHs) and Base Band Processing Units (BBUs). A Portugal countrywide network (cell site locations), with some thousands of base stations, was taken as application example.

The number of BBU Pools required to support the set of cell sites positioned countrywide was analysed. It decreases with the maximum fronthaul delay increase, from 273 BBU Pools for 75 μs to 56 for 200 μs; a rational model fits very well this behaviour. The share of single site BBU Pools was assessed, the maximum pooling gains being achieved for 150 μs of maximum fronthaul delay. The maximum, minimum and average fronthaul delay and fronthaul distance evolution were examined, as well as their standard deviation; for both quantities, a linear increase in their average and standard deviation with the maximum fronthaul delay is observed, the average values being significantly below the imposed maximum constraint. The minimum fronthaul delay is zero in every case, due to the ever positive share of single site BBU Pools, and consequently this exact scenario translates into an always null minimum fronthaul distance. Regarding fronthaul distance, the spreading of cell sites along the BBU Pools coverage areas has quite an influence, where in rural areas the sites are more or less equally scattered, as opposed to urban areas, where sites tend to be more concentrated near the BBU Pool – for these purpose, BBU Pools were divided in three classes (Urban, Suburban and Rural) according to the number of sites within their coverage area.

Network virtualisation has been introduced as a tool for large scale experimental networks, but it is also proposed as an approach for a future Internet architecture. The definition and benefits of network virtualisation is a common understanding among all architecture proposals. The main goals to achieve through virtualisation are the isolation of physical network resources, and the holding of multiple independent and programmable logical networks. Implementing multiple network architectures on top of the isolated logical networks allows for a meta architecture, where multiple architectures and testbeds for experimenting new architectures are enabled. The operation of such multiple networks leads to user and application specific logical networks, as well as to new business models for operators.

Several strategies for the provision of physical capacity to multiple Virtual Base Stations (VBSs) with different type of requirements have been presented and evaluated. The management of radio resource sharing is based on the perspective of Virtual Base Stations as an aggregated connectivity resource abstracted from a group of Radio resource Units of different Radio Access Technologies, allowing to benefit from Cooperative Radio Resource Management strategies. Instead of looking at wireless virtualisation from the perspective of the instantiation of virtual machines in the wireless nodes, our view is the virtualisation of the wireless access to provide a contracted capacity to the Virtual Network Operator, in order to serve its end-users. Three situations have been explored: the number of VBSs is increasing for all services in the same way, one VBS per service (Harmonised case); the number of guaranteed bit rate (GRT) VBSs increases by one for each GRT service, while the number of best effort (BE) VBSs is maintained with two VBSs for each service (GRT case); the number of GRT VBSs is maintained with two VBSs for each service, and the number of BE VBSs increases by one for each BE service (BE case). As an overall conclusion, one can say that the percentage of leased GRT capacity over the physical one is the main factor to take into account for physical capacity sharing, superseding the number of created VBSs. This analysis confirms the need for establishing a limit for the data rate contracted by GRT VBSs, independently of the number of VBSs, in order to allow an efficient use of Radio resource Units among all the VBSs deployed within a cluster.

Bringing your attention to a matter in this issue of the Newsletter

Body Area Networks (BANs) will be strategic actors of the next generation of wireless systems beyond the fourth generation, supporting the world of everything for connected devices and objects. Potential scenarios include monitoring of biological signals in healthcare care units, as well as elderly people monitoring in home environments. The data collected by the wearable sensors can be used either in the network itself or forwarded to any appropriated external one (e.g., emergency services). A novel model is proposed using a smart and cooperative configuration of the wearable nodes, i.e., using clusters of nodes and combining multiple independent paths to behave like multi-antennas systems (i.e., Virtual MIMO). The aim is to enhance the reliability of communications and to overcome the effects of deep fading, which can be critical for some applications (e.g., life support decisions). Different metrics are proposed for the selection of the best wearable nodes, namely, the relative MIMO capacity gain (ratio between the MIMO capacity and the maximum throughput from the SISO branches), and the configuration score (relative capacity of a selected 2×2 configuration in relation to the maximum theoretical capacity of a particular BAN).

This approach is supported by a channel model that considers the received signal composed of an on-body component (obtained from full wave simulations) and of several multipath components present in the environment (obtained from a geometrically based statistical channel model adapted to BANs). The model includes realistic body dynamics (taken from motion capture analysis). The case studies of the data sensors on the head (front and back), on the ears or on the arms, while the sink is on the front of the body (e.g., belt) are analysed. In case of the head-belt connection the signals are balanced, but, being highly correlated due to the short distances and similar propagation conditions and relative MIMO gains are small (1.57). If the data sensors are moved to the ears, higher relative MIMO gains are achieved (1.81). The trend of the average capacity over time when the sensors are on the arms exhibits higher fluctuations when compared to the placements on the head/ears, corresponding to the arms swinging, leading to an average gain of 1.73. Nevertheless, the performance of the selected virtual MIMO case studies (with relative MIMO capacity gains ranging in [1.57, 1.81]) is always enhanced when compared to the best SISO scenario, even for line-of-sight branches.

The selection of the optimum placements should be done according to the specific system under study. The best performance for the analysed case studies corresponds to the sensors on the ears, reaching a configuration score of 0.76.

The whole GROW team, as well as many other colleagues from IST and ISCTE, were involved in the organisation of EuCAP’2015 (The 9th European Conference on Antennas and Propagation — www.eucap2015.org), held in Lisbon, on April 12th-17th. The conference reached almost 1 300 participants, from 55 countries around the whole world, presenting more than 1 000 papers. We dare to say that the conference was a success, since most of the feedback we got from participants was very positive. It was pleasure to host all our colleagues.

Bringing your attention to a matter in this issue of the Newsletter

I was invited to be part of the team evaluating a Collaborative Research Centre at the Technical University of Dresden, Dresden, Germany, working on a project, Highly Adaptive Energy-Efficient Computing (HAEC). Given its very interesting goals, I dare to copy some information from their website (tu-dresden.de/forschung/forschungskompetenz/sonderforschungsbereiche/sfb912).

“The way we use the Internet today has an enormous ecological impact on the increasing energy demand of modern society. For example, the electricity required by the servers that make up the Internet relates to about 2% of the overall electricity consumption in the US and to about 26% of the overall energy consumption in Germany. Certainly a straightforward way for improving energy efficiency would be to reduce the energy consumption of every individual hardware component involved. However, for many components the optimal energy performance point has already been reached. More important is an understanding of how software can adapt to hardware components and vice versa to address the computational problems of modern society in an energy efficient way. This requires new methods and tools to write energy-aware programs, new ways of interaction between the individual pieces that collaborate to solve a problem, new communication technologies to enable this interaction between pieces that are spread across highly scalable parallel systems, and a new multi-layer coordination infrastructure to bring together these technologies. In other words, we need an integrated approach for highly adaptive energy-efficient computing to approach energy-efficient computing at all involved technology levels. the circuit level, we focus on innovative ideas for optical and wireless chip-to-chip communication. At the network level, we research secure, high performance network coding schemes for wired and wireless board-to-board communication. Innovative results at the hardware/software interface level will include energy control loops, which allow hardware to adapt to varying software requirements and vice versa. Software development in general is supported by energy-aware runtimes, energy-aware resource, stream and configuration management schemes and by an analysis framework for high performance/low energy applications. New internet applications are supported by innovations in energy-aware service execution. And, last but not least, formal methods are developed to offer a new quality of assurance in our systems of tomorrow. Demonstrating our results in a joint prototype – the HAEC Box – our goal is to become a pace setter for industry and academia on the design of future energy efficient-computing systems.”

The goal in the virtualisation of radio resources is to serve multiple Virtual Network Operators (VNOs) over the same physical infrastructure, while offering isolation and flexibility in addition to network element abstraction and multi-RAT (Radio Access Technology) support. Instead of splitting the available radio resources among VNOs, they are aggregated and jointly manage by a higher level entity. VNOs request wireless capacity from a set of physical network providers to serve their subscribers, thus, not having to deal with the physical infrastructure, but rather only with the required capacity. This approach offers pay-as-you-go Connectivity-as-a-Service to VNOs, while enabling new business models for network operators and infrastructure providers. As illustrated in ‎the figure, the key concept of Virtual RAN (VRAN) corresponds to the one of Virtual Machines (VMs) in computing. In RAN virtualisation, in contrast to RAN sharing, the physical infrastructure is not transparent to the clients. By means of isolation, services with different protocols, algorithms, and requirements for quality of service can be offered over the same physical infrastructure.
